Two dozen Kemp's ridley sea turtles are rehabilitating in Florida after cold waters off Cape Cod left them with frostbite and pneumonia.

A vanishing species of whale gave birth to few babies this birthing season, raising alarms among scientists and conservationists who fear the animal could go extinct.

Scientists who study a critically endangered species of whale that lives off New England say encouraging early signs suggest the animals could have a strong season for feeding and breeding.

Scientists say an unprecedentedly bad year for beached dolphins on Cape Cod might have to do with warming waters changing the availability of the animals’ food.

The recent stranding of more than 100 dolphins on Cape Cod is the largest such event involving dolphins in U.S. history.

Animal rescuers were trying to keep dozens of dolphins away from shallow waters around Cape Cod after 125 of the creatures earlier stranded themselves.

The decline of one of the rarest whales in the world appears to be slowing, but scientists warn the giant animals still face existential threats from warming oceans, ship collisions and entanglement in fishing gear.

A coalition of environmental groups is calling on the federal government to enact emergency rules to protect a vanishing species of whale from lethal collisions with large ships.

A new hospital for stranded dolphins is opening on Cape Cod this month and is expected to improve survival rates and enhance research.

A New Hampshire man celebrating his birthday with his three daughters saw something so rare that even marine scientists are jealous: three whales leaping from the water in near perfect unison.

A review of the status of a vanishing species of whale found that the animal’s population is in worse shape than previously thought.

A federal appeals court has blocked proposed restrictions aimed at saving a vanishing species of whale, saying they could put thousands of commercial fishermen out of work.

Scientists monitoring the white shark population in the waters off Cape Cod are attaching better sensors to the predators, including cameras.

The scientific nonprofit that tracks the white shark population in Cape Cod waters identified 55 new individual sharks during its most recent research season, but experts say that’s no reason to be afraid of going in the water this summer.

The U.S. government has denied a request from a group of environmental organizations to immediately apply proposed ship-speed restrictions in an effort to save a vanishing species of whale.

The decline of an endangered species of whale slowed last year as it lost about 2% of its population.

The federal government is close to releasing new rules that the shipping industry might have to comply with to help protect a vanishing species of whale.

A group of scientists and ocean life advocates says a type of whale that is one of the rarest marine mammals in the world lost nearly 10% of its population last year.

Cape Cod is slowly embracing its shark reputation, three summers after the popular vacation destination saw its first great white shark attacks in generations.

Henri is now a hurricane.

New Englanders bracing for their first hurricane in 30 years are hauling boats out of the water and taking other precautions as Tropical Storm Henri barrels toward the Northeast coast.

A commercial lobster diver who got caught in the mouth of a humpback whale off Cape Cod in Massachusetts says he thought he was going to die.

Cape Cod National Seashore Chief Ranger Leslie Reynolds warned at a news conference that the powerful predators are coming close enough to shore to be a concern for swimmers. Officials in Orleans also have documented at least two shark attacks on seals in recent days, the Cape Cod Times reports. Most tend to favor the Atlantic Ocean-facing beaches where seals tend to congregate, but researchers have found them off nearly every part of the Cape. More pilots have volunteered to radio in shark sightings as they fly over the peninsula, said Heather Doyle, co-founder of Cape Cod Ocean Community, a local group that advocates for white shark surveillance and detection measures. The Atlantic White Shark Conservancy, a Chatham-based research group, is also offering its Sharktivity smartphone app, which allows users to report and track shark sightings.
